A person, male or female (but typically male), who visits the UCSC campus during first rain, in hopes of seeing naked college kids running around. They often have either trucks, cameras, or both.
*After getting in the bed of a truck to get a ride back home after the first rain celebration, naturally, everyone in the truck other than the driver is naked*
"So you look kind of old to be a college kid."
"I don't go here. I just like to come up when it rains."
"Eww, first rain creepers."
